ARTHUR J. TOVNER, OF SANTA ANA, CALIFORNIA.

SPECIFICATION forming part of Letters Patent No. 700,581, dated May 2o,1902.

Application filed March 7, 1902.

To @ZZ whom it may concern:

Be it known that I, ARTHUR J. 'lowNEma citizen of .the United States,residing at Santa Ana, in the county of Orange and vStateof California,have made certain new and usefulproved means for opening and closingthe,

two hooks and holding them closed together when in use. The deviceemployed for this purpose is an eccentric, which is peculiarly arrangedand rigidly connected with a loop to which a strap is attached inpractical use.

The details of construction, arrangement, and operation of parts are ashereinafter described, reference being had to accompanying drawings, inwhich- FigureA 1 is a face view of my improved snap-hook. Fig. 2 is aface view of one of the hooks, and Fig. 3 is a similar view of theother. Fig. 4 is a side edge view of the complete snap-hook, the lowerportion being in section in order to show the arrangement of theeccentric and the pivot. Fig. 5 is a perspective view of the eccentricattachment.

A and B indicate the two hooks, having iiat Shanks l and 2,respectively, which are placed in contact, as shown in Fig. 4. The hookA (see Fig. 3) is provided with a lengthwise slot 3 and the hook B witha polygonal opening 3 to receive the pivot D. As shown in Fig. 4, suchpivot is rigidly secured to the shank 2 of hook B, but is free to slidein the slot 3 of hook A. The pivot is headed at each end, so as to holdthe hooks in easy working Contact. The lower portion of the shank l ofhook A is provided with a circular opening 4, which receives theeccentric 5 (see Fig. 5)v of the device C. The latter has on one side atrunnion 6, whichpasses through one of the jaws of the strap-loop .E-and, is headed or flanged, as shown. On the opposite side of theeccentric 5 is atrunnion having a cylindrical portion 7 and a polygonalportion 8. (See Fig. 5.) The cylindrical portion 7 passes through and isadapted to rotate in a circular opening 9, provided in the shank 2 ofhook B, (see Fig. 2,) and the polygonal portion 8 is secured in a jaw ofthe strap-loop E and nion.

Serial No. 97,084. (No model.)

flanged or headed, so that all the parts A B E are held secu relytogether, but are at the same time free to rotate upon each other, aswill now be described. lt will be seen from Figs. i and 5 that thetrunnions 6, 7, and 8 ot' the eccentric 5 are alined or, in other words,at right angles to the plane of the eccentric. It now the strap-loop E,which, as before stated, is rigidly connected with the polygonal portion8 of the eccentric trunnion and rotatably connected with the oppositetrunnion 6, be turned from the position shown in full lines, Fig. l, tothe position shown in dotted lines,same figure, the eccentric 5 will bemoved 'hold the two hooks close together or engaged,

so that they are, in effect, one hook; but when the'strap-loop is swungout of the position the two hooks will beV supported so as to allow themto be easily attached to or disengaged from a ring or other connectedpart. It is apparent that in .this yoperation the hook A has a slidingmovement in addition to its rotary one-that is to say, it has a combinedrotary and reciprocating movement which is permitted by the slot 3 andthe pivot D.

It will be seen that while one eccentric disk 5 suffices to eect thedesired movement of the hooks upon each other two such disks might beemployed, one for the hook A and .the other for the hook B, and that insuch case the second eccentric disk would take the place of thecylindrical portion-7 of thetrun- (See Fig. 5.) Y v l As thusconstructed vthe jaws or hooks proper of my improved snap-hookl are heldsecurely locked together when the latter is in use, but may be easilyand quickly separated for attachment and detachment.

'Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

ICO

l. An improved snap-hook of the class described, com prisingtwo hooks orjaws having iiat Shanks which are placed in contact, an eccentricarranged in a corresponding'opening in one of the Shanks and havingtrnnnions as specilied, and a strap-loop which is rota.- tably connectedwith one of said trnnnions and rigidly connected with ythe other,suhstantially as shown and described.

2. The improved snap-hook of the class described,rcomposed of two hookshaving flat Shanks, one of which is provided with a lengthwise slot anda circnlaropening, a pivot passing through said slot and the oppositehook, and an eccentric disk arrangedA in the said circular opening andIhaving 'trunnions one of which extends through and is rotatable in theopposite shank, and a strap-loop which is rotatably connected with oneof said trunnions and rigidly connected with the other, whereby, whensaid loop is thrown upward from the normal position, the said hooks areseparated in the manner shown and described.

3. An improved snap-hook of the class described, composed of two jaws orhooks proper, which are pivotally connected, and an eccentric which isapplied to the Shanks below the said pivot, and a strap-loop rigidlyconnected with one of the trunnions of said eccentric, substantially asshown and described.'

4. The eccentric attachment for a twin snap-hook consisting of a diskhaving trunnions arranged eccentrically, and alined as shown anddescribed, whereby the device is adapted for operation in vconnectionwith hooks and a strap-loop in rthe manner specified.
